Medical Microextrusions | Process, Benefits, and Examples

Advancements in medical microextrusions technology in recent years have allowed manufacturers to create high quality products for the world of medical OEMs. With a range of dimensions that can reach as small as 0.024 in., OD with up to 6 lumens, and an ID range that can reach 0.003, it’s no surprise that many OEMs are turning to companies like Taber Extrusions that can provide products within these parameters.

In fact, micro-sized medical components are quickly becoming crucial to modern hospital safety and cost-efficiency. Whether it be for micro-tubing or micro sized components, the microextrusion process provides a number of benefits to engineers, OEMs, and patients.

In the quest to create higher quality medical devices, companies are looking to enhance existing products (including catheters and precise flow restrictors) through miniaturization, while ultimately reducing the costs of production.

Medical products that utilize microextrusion technology overwhelmingly support cardio-and-neurovascular procedures, drug delivery, IV procedures, and other procedures that require work on a micro level.

By minimizing the impact of invasive procedures, the medical industry can reduce complications, make procedures faster and more efficient, and ultimately reduce patient in-time and overall healthcare costs.

WHAT’S THE MICROEXTRUSION PROCESS LIKE?

Manufacturing the miniature components used in a medical microextrusion device poses a unique challenge for microextrusion providers. These components cannot be created using conventional extrusion machinery. Instead, they require precise, state-of-the-art equipment that allows for a high degree of precision and control over the process, as well as Engineers and technicians that possess deep knowledge of both the material and the process itself.

However, at its core, the process is similar to that of regular extrusion.

The material is either pushed forward (direct) or pulled through (indirect) a die orifice to create the shape required. Unlike macro-level extrusions, microextrusions are extruded at a very slow rate to maintain the physical properties of materials that are often delicate.

Done properly, microextrusions can create end products that have complex cross sections and preserved chemical properties.

BENEFITS TO OEMs

Lower Time-to-Market

In years previous, OEM’s requests for medical products would require them to re-outfit their existing extrusion machines, which would take more time and far less efficient. With many manufacturers outfitting themselves with microextrusion machinery, the time required to create the product is drastically reduced.

Lower Costs

As stated above, microextrusions can achieve their desired performance at fractions of the cost, due to the lower cost in materials that are used. As the development of the technology continues to improve, so to do the devices that are used in tandem with them. (i.e fibre optic cable, sensors, stints, etc.)

Psychological benefit to patients

A patient’s positive mental state can be a great asset to their recovery. Waning are the days of large, invasive medical devices that can cause patients discomfort. Smaller, less intrusive devices can go a long way. (source: Medical Plastic News)

About Taber Extrusions

Founded in 1973, Taber Extrusions originally pioneered a process for extruding rectangular billet which enables the company to extrude solid profiles up to 31 inches wide or hollows up to 29 inches. Taber expanded with the purchase of an extrusion facility in Gulfport, MS in 1995 which houses a new state of the art cast house, two additional presses, and a fabrication area that has been expanded multiple times. Taber continues to extrude billet in a wide range of alloys. and sizes.
